High‐Order Projection‐Based Upwind Method for Simulation of Transitional Turbulent Flows

International Journal for Numerical Methods in Fluids, EarlyView.
In this study, we evaluated the implicit large‐eddy simulation capabilities of the mass‐conserving mixed stress method for transitional turbulent flows and proposed an efficient solution method for large‐scale applications. The results presented in this work show promising outcomes for incompressible aerodynamic flow problems, which can be further ...

Simulation of an Isolated Tiltrotor in Hover with an Unstructured Overset-Grid RANS Solver [PDF]

, 2009
An unstructured overset-grid Reynolds Averaged Navier-Stokes (RANS) solver, FUN3D, is used to simulate an isolated tiltrotor in hover. An overview of the computational method is presented as well as the details of the overset-grid systems.

The Role of Energy Transition, Digitalization, and Green Goods in Material Footprints and Sustainability

Sustainable Development, EarlyView.
ABSTRACT This study investigates how green and non‐green goods, energy transition, digitalization, economic growth, and population affect the material footprint of G‐7 countries from 1990 to 2023. Using an extended STIRPAT framework, we show that green and non‐green goods increase material footprint, demonstrating the resource intensity associated with

Labor Supply and Firm Size

International Economic Review, EarlyView.
ABSTRACTLarger firms feature (i) longer hours worked, (ii) higher wages, and (iii) smaller (larger) wage penalties for working long (short) hours. We reconcile these patterns in a general equilibrium model, which features the endogenous interaction of hours, wages, and firm size. In the model, workers willing to work longer hours sort into larger firms

High-order residual-based compact schemes for compressible flows on overset grids

, 2014
Residual-Based Compact (RBC) schemes have been developed for the simulation of compressible flows in the finite difference framework and extended to curvilinear grids via a structured finite-volume formulation.

WakeMeta: Physics‐Guided Graph Meta‐Adaptation for Cross‐Farm Probabilistic Wind Power Forecasting

Wind Energy, Volume 29, Issue 12, December 2026.
ABSTRACT Short‐term wind power forecasting is essential for reliable grid operation, yet newly commissioned wind farms often provide only limited supervisory control and data acquisition (SCADA) histories for model adaptation. Existing cross‐farm methods face two related limitations: Data‐driven models must relearn site‐specific interturbine ...
